I know there is a lot of hope in Canada he's going to be back for the Olympics. No chance of that/could that be a place to knock the rust off if ready then?

Not entirely, because he needs to get a feel for working with this particular set of teammates again and there will be a ripple effect throughout the lineup because everyone's roles will be adjusted slightly. That'll take at least a game or two to shake out (Cooper's teams are, admittedly, extremely good at making those adjustments quickly).
